Electrostatic actuation is a common method used to drive microelectromechanical systems (MEMS) devices. The activation is achieved by applying a voltage difference between opposite electrodes of a deformable capacitor. Currently, DC-bias line arrangements in electrostatic actuators substantially impair radio frequency performance and introduce power loss.

Purdue University researchers have developed a DC-bias line arrangement that permits electrostatic actuation of MEMS actuators for tunable microwave resonators and filters. It can achieve electrostatic actuation without compromising performance or introducing power loss.
